side-channel attacks
About this tag
Side-channel attacks exploit indirect information leakage from computer systems, such as timing variations, cache behavior, or thermal emissions, to bypass security defenses. On Windows 11, researchers have demonstrated cache timing side-channel attacks that break Kernel Address Space Layout Randomization (KASLR), a key kernel memory protection. These attacks leverage processor cache behavior to infer memory layouts, undermining a core security mechanism. Microsoft's Patch Tuesday updates, including the July 2025 release, address numerous vulnerabilities but side-channel attacks remain a persistent challenge. Discussions on WindowsForum cover KASLR bypass techniques, the role of memory-safe languages like Rust in cryptographic libraries, and even AI-driven thermal attacks that recover passwords from keyboard heat traces. Understanding these evolving threats is critical for Windows users and administrators.
